comment that asserts the author concluded "rightly".

The Incredible Regularity of Periodic Abrupt Climate
Change
------------------------------------------------
Reference
Rahmstorf, S.  2003.  Timing of abrupt climate change:
A precise clock.  Geophysical Research Letters 30:
10.1029/2003GL017115.

What was done

The author analyzed the GISP2 ice core record from
Greenland with respect to the timing of
Dansgaard-Oeschger (DO) warm events.

What was learned

In the words of the author, these abrupt climate
changes "appear to be paced by a 1,470-year cycle with
a period that is probably stable to within a few
percent."  With 95% confidence, for example, the
period is maintained to better than 12% over at least
23 cycles during the time interval 51 to 10 thousand
years BP.  In fact, Rahmstorf reports that "the five
most recent events, arguably the best-dated ones, have
a standard deviation of only 32 years (2%)."

What it means

Rahmstorf concludes, and rightly so, that this finding
"strongly supports the idea that the events are paced
by a regular 1,470 year cycle" and that "the highly
precise clock points to an origin outside the Earth
system."  He also notes "there is some evidence that
this cycle may also be present in the Holocene but
does not trigger DO events then, possibly because the
Atlantic ocean circulation is not close to a threshold
in a warm climate," suggesting further that "the
so-called 'little ice age' of the 16th-18th century
may be the most recent cold phase of this cycle."
Taken together, these observations suggest that the
warming of the past century or so is likely nothing
more than the logical next phase of this repeating
pattern of cyclical warming and cooling that is paced
by some highly regular extraterrestrial forcing
factor.
